PDT (PDTools) Metallic CBN Stone 4"

CBN stone on copper-tin metallic bond for Hapstone sharpeners, made by PDT / PDTools Factory.

Binder

M1001 metallic bond

The stone uses the improved M1001 copper-tin binder with nickel and titanium added for longer work and reduced loading.

Abrasive

CBN productivity

CBN stones are among the most productive, efficient, and durable abrasive stones for sharpening work.

Concentration

100% concentration

High performance is achieved with 100% CBN concentration, while the copper-tin bond holds abrasive grains firmly in place.

CBN vs diamond

Softer work with a cleaner scratch pattern

CBN works softer than diamond and does not leave such deep scratches on the cutting edge during sharpening.

Diamond has a tetrahedral crystal structure, with fewer cutting edges and sharper cutting angles. CBN has an octahedral crystal structure, with more cutting edges and less aggressive angles.

This gives CBN higher productivity with a smoother working feel.

Authenticity

Hapstone is the official representative of PDT / PDTools, so you can be sure that you are buying original PDT products.

Inexpensively Cute, Resilient and Durable...
Size: 5 Big Kid, Color: Purple, Size: 5 Big Kid, Color: Purple
Purchased these cheap mesh-like breathable, high quality light-weight canvas material non-reputable, off-brand name sneakers for my stepdaughter because her puma sneakers were wet. My daughter loves them; not only are they her favorite color, she says they're very comfortable and easy to put on. They're easy to put on, with a slip on style and also have tie up for a tighter fit. My daughter also says likes the purple in-sole bubble that looks like a real air bubble but its really hard plastic volcanized to give a nice polished purple color finish. My daughter is happy with them, so I am too. They're well worth the practical cost, I look forward to them lasting a growth period of approximately six months to a year. Highly recommended. Pick you child's favorite color! You'll be happy you did...
